I tried to use socat so I could monitor the serial connection: sudo socat -v -d -d pty,raw,echo=0 file:/dev/ttyUSB0,raw,echo=0,b57600 That creates a pty and a bidirectional passthrough to /dev/ttyUSB0, echoing the traffic to the screen. I ran owfs with -d /dev/pts/2, for that is the PTY that socat printed out. Somehow, that ended up resetting the LinkUSB to 9600 baud, which seems to have been key to getting better behavior. By the way, when using socat, I couldn't run owfs with "--link=/dev/pts/2" because I got a "cannot access device" message even though I was running as root. Anyway, now that the LinkUSB is 9600 baud, running sudo /opt/owfs/bin/owfs --baud=9600 --link=/dev/ttyUSB0 -m /var/lib/1wire works, partially. The directory shows the structure I expect to see, but I don't see any devices: # ls /var/lib/1wire bus.0 settings statistics structure system uncached There is a temperature sensor on it, so I would expect to see something.
